"My 2003 Ford Focus was having an idle problem and was not getting the gas mileage that it used to. A friend suggested the oxygen sensor and as the car had 180 000 miles on it I decided to try that first. The selection on site was great and their prices are very competitive. I ordered the part and installed it the same day it arrived. The idle was back to normal and after a few longer drives I could tell that the gas mileage was back up to where it should be. It seems to have done the job."posted by: Mike on January 19, 2015view all 8 reviews

"The sensor was shipped on time. However, it was not compatible with my system. I kept getting engine flaut codes. The problem still has been resloved."
